The study was designed for mapping the filariasis transmission risk using geo-climatic variables. The application of remote sensing and GIS in the present study is mainly focused on profiling the areas at risk of filariasis transmission. The filariasis disease is caused by the Culex genus mosquito vector. The survival and longevity of infected filariasis vector mosquitoes are spatially determin...

Media sharing applications, such as Flickr and Panoramio, contain a large amount of pictures related to real life events. For this reason, the development of effective methods to retrieve these pictures is important, but still a challenging task. Recognizing this importance, and to improve the retrieval effectiveness of tag-based event retrieval systems, we propose a new method to extract a set...

Item non-response is a challenge faced by virtually all surveys. Item non-response occurs when a respondent skips over a question, refuses to answer a question, or indicates that they do not know the answer to a question. Hot deck imputation is one of the primary item non-response imputation tools used by survey statisticians. Recently, new competitor in the field of Weighted Sequential Hotdeck...

The first study for this dissertation develops a tax-adjusted cost-of-carry model for Australian stock index futures and estimates the value of the debt tax shield, cash dividends and imputation tax credits flowing from the basket stocks in the index. As discussed in the previous chapter, the study relaxes the assumption made in previous research that interest and dividends receive the same tax...

managing Multiple imputation can improve data quality.

A country with a surplus river basin cooperates with a country with a deficit river basin in a joint investment project to build a water canal. The benefits from the existence of the canal are realized when cooperation halts and countries will have the opportunity to engage in a non-cooperative water market game. We define an imputation distribution procedure to share the “burden” from cooperat...

This paper presents a framework for the construction of a residential real estate price index for Jamaica. This real estate price index will consist of a sales value-weighted aggregation of price sub-indices across geographical regions or zones. In this study, a hedonic price imputation model for housing in the parishes of Kingston & St. Andrew is estimated using mortgage transaction and assess...

In the Pre-Elementary Education Longitudinal Study (PEELS), imputation of item missing data was done using AutoImpute (AI) software, which uses semi-parametric modeling to form imputation classes. In this paper, we summarize PEELS experience with AI, investigate the bias aspect of the imputed data for the PEELS teacher questionnaire data, and study the variance estimation of imputed data using ...
